To all whom it may concern:

Be it known tha 1, JOHN PLANT, a citizen of the United tates, residing at Doug las, territory of Alaska, have invented certam new and useful Improvements in Shoe- Heels; and I do "hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in-the art to which it appertains to make and use the same.

p This invention relates to improvements in heels for boots, shoes and other foot coverings.

An object of the present invention resides in the provision of a cushioned heel section so associated with a shoe as to be self-adjusting and thereby evenly distributethe Wear throughout its surface.

A further object of the invention is to provide a heel section of the above character, embodying means-of novel construction alllid arrangement for its attachment to a s 0e. c

With the above and other objects of similar nature in view, the invention consists in the construction, combination and arrangement of parts set forth in and falling within the scope of the appended. claim.'

In the drawings:

Figure 1 is a bottom plan view of the'rear portion of a shoe with the invention assoziated therewith. y I

Fig. 2 is a longitudinal sectiontaken on ;he line 2-2 of Fig. 1.

Fig. 3 is an enlarged fragmentary view )f the central portion of the device, and

Fig. 4 is a perspective view of one of the vear plates or washers removed. I

Referring now more particularly to the tccompanying'drawings, there is illustrated helrear' portion of a shoe 5 including the The invention is shown generally at 8 and omprises a cushioned disk, constructed prefrably of highly resilient material such as ubber or similar substance, molded or other- Iise suitably formed to provide in its wearug face a central circular recessor counterunk portion 9 having an opening 10 in the ase thereof. Seated within the recess 9 is wear plate or washer 11, flat and of a dimeter slightly less than the surroundmg all of the recess so as to fit snugly agalnst 1e base of the latter. Also seated within 1e recess 9 is a second wear plate or washer 2 of such construction as to present a mumrotatably' engaged upon the first mum of bearing surface 13 upon the adjacent face of the plate 11. This plate 12 is centrally depressed as at 14 away from the plate 11 and is further provided with an aperture 15 the walls of which are tapered toward theplate 11, the latter being likewlse apertured as at 16 to aline with the aperture 15 and with the opening 10 in the base of the recess.

In applying the disk, the same is disposed upon the under ,face of the heel 6 as illustrated in Figs. 1 and 2, the plates or washers 11 and 12 being placed, in. the manner shown, within the recess 9 and a screw 17 inserted through the alined openings in said plates and disk anddriven into the heel as is apparent. The disk is thus securely positioned on the heel while being free to rotate on the screw 17, and as it is the natural tendency when walking to strike the floor or other surfaces "at a point to one side of the longitudinal center of the shoe the disk will be caused to revolve slightly and thus evenly distribute the wear throughout its surface. 7

It will be observed that the plate 11 is frictionally held stationary with respect to stationary by the tapered head of the screw 17, so that during rotation of the disk the ,the disk whilethe plate 12 is similarly held plate 11. will move with respect to the plate 12 and thereby present wear upon the reduced portion of the disk.

It will further be noted that the disk is also provided in its wearing face with a circular series of recesses 18 which recesses serve as suction cups to prevent slipping of the wearer.

It will also be observed that as the disk is compressed the outwardly curved periphery of the plate 12 will serve as a scraping edge to loosen from the wall of the recess any accumulation of foreign matter, while it will also tend to prevent the entry of such matter between the plates 11 and 12 where its presence would materially decrease the emcient operation of the heel.

What is claimed is:

A shoe heel comprising a resilient disk provided with a central recess having an opening through its base, a flat wear plate seated in the recess to frictionally engage the base thereof and rotate with the disk, a second wear plate seated in the recess and named plate, said second plate being centrally dein the base of the recess, and a screw en- 1,2sa,soe

gaged through said alined apertures and. 10 olpening and adapted to be driven into a s 0e.

In testimony whereof, I afiix my signature, in the presence of two witnesses.
